PDFfiller is a GREAT program with INCREDIBLE customer service! PDFfiller is a GREAT program! It is very easy to use. It helped me tremendously when I had a project and needed to fill out literally hundreds of documents online. The program worked very well, was incredibly responsive, & even kept all of my documents for easy access as well. Most importantly, however, is that they have absolutely INCREDIBLE customer service! I used the chat feature and it was totally painless and even enjoyable. I was treated very well by the chat rep (Paul)! I am a single mother who is trying to start a small business with VERY limited funds. I meant to cancel my plan before my 30-day trial was over. Like so many other times in my hectic life, I guess I forgot! I was quite anxious about it as many companies charge high cancelation fees if you fail to cancel during the trial. There was no need to worry though. I simply logged into my account and then I saw the chat feature. I chose to use it even though I was hesitant to do so (many companies do not provide very good customer service through chat). The response time was extremely fast. I asked to cancel my membership and he replied right away that he would do that for me. Here is the best part, he then proceeded to ASK me if I would like a refund as well!! Now that is WONDERFUL CUSTOMER SERVICE!! Thanks so much, PDFfiller & Paul! I will definitely use them in the future and recommend them to my family and friends. You just do not see that level of customer care combined with great products anymore. I was quite impressed!

no problems so far no problems so far, only thing I don't like is that the forms you search for come from google and isn't always the same thing you are searching for.

Even though I didn’t use their website Even though I didn’t use their website, I am very satisfied with the customer service. I have subscribed and forgot about it and it took the money from my account. I contacted customer support and my issue was solved in less than a minute! If anyone has the same problem, don’t worry, just contact them and they’ll help! :)

Customer Service Is Great I used this service while at work and as a functional feature it is great, does what one needs it to do. However, as sometimes happens, I needed to charge this to my personal banking account at the time. When I left the company, I contacted their customer services team via their web based chat service and a kind lady named Monica answered my query. She was very helpful, diligent in helping me locate my details, and took her time to reassure me that the service subscription had ended and evening was a-ok. I know if I ever need to use this service I will come back, and part of the reason is because the customer care was absolutely spot on. Would recommend.
